Operation at base frequency or higher

The output frequency is 55 Hz. (For V/F control)When the base frequency is set to 50 Hz, frequencies over 50 Hz is the constant output range.Note that the ma... More Details >>

Parameter setting

Check if Pr.13 (Starting frequency) is set to higher than 10 Hz.Also check if a signal is input through the terminal MRS. More Details >>

Comparison of noise with FR-A200

The setting ranges of the carrier frequency are:- FR-A200: 2 kHz to 14.5 kHz- FR-A200EXCELLENT: 0.7 kHz to 14.5 kHzThe range of the FR-A200E is extended to t... More Details >>

DIN rail installation

You can do it by using the optional DIN rail attachment (FR-DU01/02). More Details >>

I want to shorten deceleration time of small capacity motor

You can use an inverter with a larger capacity than the motor. You cannot connect a brake resistor to the FR-E520-0.1K and 0.2K. With the FR-E520-0.1K or 0.2... More Details >>

Relationship between frequency and load current

If the load is heavy and the output current is higher than the control value, you can adjust Pr.22 (Stall prevention operation level) to trigger the stall pr... More Details >>

Inverter control power supply

The FR-E540 uses common input for the control power supply and main circuit power supply. (It has only one power supply input terminal.) Therefore, you canno... More Details >>

Watt-hour meter clear and operation hour meter clear
